1 Claim. gor. 97-40) The present invention relates to new and useful improvements in farm implements and has for its primary object to provide a machine adapted for working the soil and also for breaking'up'the hard lumps of earth over which the machine is traveling.
An important object of the present invention is to provide amachine of this character equipped with a pair of rotating soil pulverizers and providing drive means for the pulverizers extending to a power take-off from the tractor employed for pulling the machine over the ground.
A further important object of the present in-- vention is to provide a frame for the machine constructed of a pair of transverse sections hav ing a ball and socket connection and providing ground wheels for the frame on which the frame of an additional toothiconstruction, and
Figure 12 is a similar view Figure 13 is a fragmentary'sectional view taken on the line l3l3 of Figure 5. a
" Referring now to thedrawings in detail, wherein for the purpose of illustration 1 have disclosed a preferred embodiment of the invention, the
' numerals and B designate a pair of frame secis mounted for vertical adjustment to regulate the height of the pulverizing element.
An additional object is to provide rotating pulverizing members of novel construction. V
'A still further object is to provide a machine of this character of simple and practical construction, which is efiicient and reliable in per formance, relatively inexpensive to manufacture and maintain in operation and otherwise well adapted for the purposes for which the same is intended. v
Other objects and advantages reside in the details of construction and operation as more fully hereinafter. described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a top plan view,
Figure 2 is a side elevational view,

' connected to the respective shafts 22.
tions each including a pair or end plates 1 and transversely'and longitudinally extending brace members 8 and 8'. The adjacent endsof the frame members 5 and 6 are provided with front and rear longitudinally extending webs 9 and l0 having ball and socket connections II for connecting the respective frame members to each other for vertical pivotal movement. Each of the end members I are provided with bearings l2-within which a shaft I3 is journalled, the shafts of the respective frame members being connected by an extension I4 having a ball and socket connection I5 with each of the shafts l3 as-shown to advantage in Figure 4 of the draw-' 1ngs.
To the outermost end plate 1 of each of the frame members 5 and 6 is securda gear housing l6 and a'similar'gear housing I1 is also secured to the inner end plate of the frame member 5 as shown'in Figural of the drawings. A stub axle I8 is provided with anupstanding-ex: tension l9 which is inserted through each of the gear housings IS, the upper endof the extension being provided with a rack 20 engaged by a pinion 2l arranged within the housing and operated by a shaft 22. Ground wheels 23 are journaled on each of the stub axles l8.
Projecting forwardlyfrom each of the frame sections 5 and 6 are brace beams 24, the front ends of the beams converging toward each other and are connected at their front ends to a sectional plate 25, the sections of which are hinged along their longitudinal edges as at 25 on a draw bar 26, the rear-end of the bar being pivoted as at 26. Mounted on the plate 25 is agear housing 21 having a' transversely extending shaft 28 journaled therein and on which a plurality of bevel gears 29 are secured. Bevel gears 30 operatively engage each of the bevel gears 29, the bevel gears 30 being mounted on shaft sections 3| extending rearwardly through openings in the rear face .of the housing, and to each of the shaft sections 3| are attachedshaft extension 33 by means of ball and socket connections 34, the rear ends of the shaft extensions 33 being One end of the shaft 28 extends into a housing extension 35 in which a worm gear 35 is positioned and mounted on the shaft 28, the worm gear being operatively engaged by a worm 31 on a shaft 38 which projects upwardly at the front end of the machine and is provided with an operating wheel 39.
From the foregoing it will'be apparent that through the manipulation of the wheel 39 that the respective stub axles |8 may be raised or lowered whereby to vertically adjust the frame members and 6.
Secured to each of the shafts l3 of the respective frame members 5 and 6, is a cylindrical frame designated generally at 40, including a plurality of longitudinally extending spaced frame members or slots 4| and a plurality of spacing disks 42. The members 40 constitute pulverizing drums on which pulverizing teeth 43 are secured to the longitudinally extending frame members 4|.
Secured to the shaft I3 is a bevel gear 44 operatively engaged by a pinion 45' mounted on a forwardly extending shaft 46 extending into a 2 speed transmission gear housing 41 .of conventional construction and controlled by a gear shift lever 41. The gears 44 and 45 are enclosed within a housing 48 which is secured to one of the end frame members I. A shaft 48 extends forwardly from the '2 speed transmission gear housing 41, the shaft 48' having a ball and socket connection 49 with a drive shaft extension 50 which extends to a power take-off from a tractor (not shown).
The drive connection for the pulverizing members 4|! is arranged to rotate said members in the same direction as the forward movement of the wheels 23.
As shown to advantage in Figure 8 of the drawings, and pulverizing teeth 43 include a shank portion 5| adjacent the inner end of which is a conical member 52 having longitudinally extending ribs 53 formed thereon, the conical member and the ribs being adapted to conformably seat in openings 54 formed in the longitudinal frame members 4|. The inner end of the shank 5| terminates in a threaded extension 55 for receiving a nut 55 whereby to secure the teeth on the pulverizing drum.
The outer ends of the teeth'may be of any suitable construction, such as illustrated in Figures 8, 11 and 12 of the drawings.
In Figure of the drawings I have illustrated a further modified tooth construction which comprises an arcuate-shaped blade 51 having its inner edge provided with a plurality of threaded stems 58 for engaging through the openings of the longitudinal frame members 4| for attaching thereto. The blades 51 are adapted for attaching to the pulverizing drum in circumferential relation, substantially in the form of cultivating disks.
In addition to the pulverizing teeth carried by the rotating pulverizing drum, a plurality of cultivating plows P may also be attached to the frame members of the device.
The connected ends of the frames 5 and 6 are supported by a center wheel 53, having a disk 60 secured at each side thereof connected by a hub 6| on which the wheel rotates, the hub being provided with a vertically extending slotted opening 62 for freely receiving the shaft connection l4. Rising from the left of the disk is an inverted U-shaped bracket 63' having a rack 54 on one leg of the bracket engaged by the pinion of the center gear housing H for vertically adjusting said center wheel. The other disk at the right of the wheel bears against a pair of spacing ribs 65 formed on the end plate 1 of the adjacent frame having slots 50 in said right disk to allow for wheel adjustment.
From the foregoing it will be apparent that as the machine moves over the ground the pulverizing drums will be rotated so that the teeth will engage clods or lumps of earth to break the same in the desired manner.
It is believed the details of construction, operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is:
-A ground pulverizer comprising a pair of frames, means swivelly connecting the frames in endwise relation, a toothed pulverizing drum rotatably mounted on each frame, drive means for the drums, wheels supporting the outer ends of the frames and a wheel also supporting the connected ends of the frame, means for vertically adjusting theframes on the wheels and including a rack and gear construction between the frames and the wheels, shafts for the gears and a common operating device for the shafts.
